Reprogrammable option select circuit

摘要

An integrated circuit package includes an integrated circuit device that operates in more than one operational mode. The operational mode of the integrated circuit device is controlled by a mode select input. Examples of operational modes include fast page and block modes, two- and three-latency modes, and normal and test modes. A reprogrammable mode select circuit within the integrated circuit package produces a mode control signal that drives a mode select input of the integrated circuit device. The operational mode of the integrated circuit device then corresponds to the state of the mode select signal.
